SPRING-'SEAT FOR CAR-SPRINGS.

SPECIFICATION forming part of Letters Patent No. 623,942, dated April 25, 1899. 1

Application tiled April 4, 1896.

To all whom, it may concern,.-

Be it known that I, ALBERT O. BUcKIUs, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Spring-Seats for Car-Springs, of which the following is a full, clear, and eX- act description.

Figure l shows in vertical section an axlebox having a spring-seat and a spring cappiece formed in accordance with my invention. Fig. 2 is a plan view of the axle-box. Fig. 3 is a plan view of the cap-piece on a smaller scale.

In the drawings, 2 represents the axle-box. 3 is the spring-seat thereon, having a central projection 4, around which the spring 5 is set. On top of this spring is a cap-piece 6, having a disk-like head or seat, against which the upper end of the spring bears, and having a central projection 7, which iits inside the coil of the spring. In use the cap-piece is set within a socket on the under side of the bolster of the car-truck, ribs 9 being formed on the cap-piece and adapted to engage recesses at the end of the socket in order to prevent the cap-piece from turning. The surface against which the spring has a bearing on the seat 3 is plain andis constituted by forming the seat hollow,with two parallel horizontal walls b c, connected by vertical integral cross-ribs l0. These ribs afford the necessary strength to support the load put upon the seat by compression of the spring. The iiat Wall l),

against which thespring lits, gives to it a flat bearing without projections such as would cut or abrade it, and by making the seat hollow the lightness and uniformity of the thickness desirable in castings of this Serial No. 586,175. (No model.)

sort are attained. The cap-piece 6 is also made with a hollow seat and with concealed integral ribs ll hack of the bearing-face.

The advantages of the invention will be appreciated by those skilled in the art.

By forming the spring-seat with two parallel horizontal walls connectedby integral vertical ribs, as above described, a very strong construction is afforded, since the ribs support and take up the strain exerted upon the upper Wall b, and said Wall being fiat and without projecting surfaces supports the bearing of the spring without cutting or wearing it. The device so constructed is also very light in weight.

The novel features of the invention are stated in the claims.

I claim- 1. A spring-seat for car-springs, the same having parallel walls b, c, the outer Wall b presenting a 'smooth bearing-face for the spring, and having also intermediate radial integral cross-ribs connecting said walls, the planes of the walls and of the ribs being substantially at right angles to each other; substantially as described.

2. A hollow spring-seat for car-springs, the same being integral with the axle-box, the top of the axle-box forming the bottom wall of the spring-seat and being connected with the top wall thereof by integral radial crossribs, said top wall presenting a smooth surface for the bearing of the spring.
